We present a theoretical study of recent laser-alignment and mixed-field-orientation experiments of asymmetric top molecules. In these experiments, pendular states were created using linearly polarized strong ac electric fields from pulsed lasers in combination with weak electrostatic fields. We compare the outcome of our calculations with experimental results obtained for the prototypical large molecule benzonitrile (C(7)H(5)N) [J. L. Hansen et al., Phys. Rev. A, 2011, 83, 023406.] and explore…

Laser-driven torsional coherences.

The results point to the origin and consequences of the fundamental differences between rotational and torsional coherences, and design guidelines for torsion control experiments are provided by illustrating the role played by the laser intensity, pulse width, temperature, and molecular parameters.

It is shown that at molecular temperatures in the 1 K range very strong alignment is obtained already at intensities of a few times 10(11) W/cm2 for all four molecules, which is the strongest degree of alignment ever reported for any molecule.
